Version information is determined at build-time and thus there is
no need to pass it down from main. In its own package it can
be used from various other packages.
Resolves#609 by removing two dependencies on git.
- Use the Makefile to find the current directory.
- In the case of building from an archive fall back to fixed REV

The main purpose of this is to allow for blacklisting
of expensive metrics as a tactical option.
It could also find uses for renaming and removing labels

Also, rearrange and clean up some things to make this work.
The textarea starts as a single line, but auto-expands when entering
multiple lines (e.g. via Shift+Enter). Pressing just "Enter" still
executes the expression.
When prometheus starts up and is recovering its state it will not handle
SIGHUPs. If it receives those during this phase it will exit. The change
here makes prometheus ignore SIGHUPs until it is ready to handle them.
Note this is only done for SIGHUP because that signal is used for
trigger a config reload and a such something could already be sending
these signals as part of a config update.
`keep_common` is more in line with the function name
`drop_common_labels()` terminology-wise, and also more in line with
`group_left`/`group_right` (no `...ing` verb suffix).
We could also go the full way and call it `keep_common_labels`. That
would have the benefit of being even more consistent with the function
`drop_common_labels()` and would be more explanatory, but it also seems
quite long.
The YAML parser ignores additional parameters on unmarshaling. This causes
frequent confusion with bad configs that pass parsing.
These changes raise errors on additional parameters.
